COMBINED TYPE-WRITING AND COMPUTING MACHINE.

Specification of Letters Patent.

Patented Apr. 16, 1912.

Application filed December 15, $911. Serial No. 865,892.

To all whom it may concern Be it known that I, HERBERT H. STEELE citizen of the United States and resident of Marcellus in the county of Onondaga and State of llew York, have invented certain new and useful Improvements in Combined Type-Writin and Computing Machines, of which the f0 lowing is a specification.

My invention relates partly to computing machines and also to combined typewriting and computing machines.

The principal object of my invention is to prevent the computing mechanism from the full-stroke devices out of 0 placing an unnecessar load on the keys and from interfering wit the ra idity of the operation of the keys, espec ally the numeral keys, when said keys are used for other purposes than computing, as when writing outside of the computing column or zone.

Various devices have been employed in the past in combined typewriting and computing machines to disconnect the comput ing mechanism from the numeral keys when writing numbers that were not intended to be registered.

My invention contemplates, not disconnecting the computing mechanism, but throwing out of operation those parts of said mechanism that most hamper the op eration of the keys. The parts of the computing mechanism that most retard the action of the numeral keys are certain keycontrolling devices known as key arrester and full stroke devices. \Vhen these parts are in operation the key cannot return to normal position until it has made a complete movement of depression and cannot start on a second depression until it has completely returned to normal position. Moreover. a second key cannot start down until the preceding key has entirely returned to normal position. These facts necessitate a slower operation of the keys than a skilful typewriter operator is capa ble of. I have therefore provided means. in a combined typewriting and computing ma; chine. for maintaining the key arrester and ration when the carriage is not in an adding zone, and for throwing these devices into operation. when the carriage is in an adding zone.

To the above and other ends. my invention consists in certain features of construction and combinations and arrangements of parts, all of which will be fullyset forth erein and particularly pointed outin the claims One embodiment of my invention is illustrated in the accompanying drawings, in Which' Figure 1 is a side elevation, on a reduced scale and partly in section, of a Remington- Vahl typewriting and computing machine, with parts of the machine omitted or only diagrammatically represented. Fig. 2 is a fragmentary front elevation of a portion of the same. Fig. 3 is a side elevation of a portion of the computing mechanism, a con tain shoe being shown in section. Fig. 4 is a fragmentary side elevation of some of the parts shown in Fig. 3, the framework bein omitted and the mechanism being in a di ferent position. Fig. 5 is a fragmentary top view of certain of my devices, Figs. 2 to 4 inclusive are, in the pen drawings, about natural size, and Fig, 5 is on an enlarged scale.

The machine shown in the drawings, except for modifications in which my invention consists, is a W'ahl addin machine mounted as an attachment on a mington No. 11 typewriter. The frame of said typewriter comprises a base 1. corner posts 2 and a top plate 3. On said top plate are mounted stationary rails 4 of a paper carriage 5, said carriage having a platen 6 mounted therein. Said carriage and platen are here conventionally re resented, the platen having a shaft journall'd in the carria e 5. In the actual machine. the carriage inc udes a number of parts not here shown. The printing instrumentnlities consist of types 7 mounted on front-strike type bars 8 which are supported at 10 on a vertical seg ment. Said type bars are operated by horizontul links 11. sub-levers 12, vertical links 13 and printing key levers 14. the latter having printing keys 1:) on their forward ends and being provided with restorin springs 16. The carriage 5 is fed along tfie rails 4 by means of the usual spring drum and escapement mechanism, not shown.

The \Vahl adding attachment. comprises a stationary frame piece 17 which is mounted upon the front part of the typewriter frame,

bein secured to the top late 3b}: m 118 of brac ets 18. The Wahf machine also includes a carriage bar 20 -mounted .parallel with the line of travel of the typewriter carriage and in front of said carriage and supported at the middle of the machine bymeans of certain rollers 21 mounted on the frame 17 and engaging the carriage bar 20.

Said carriage bar is supported and conator 26 having a master wheel 27 which is operated from the numeral keys 15 by means including a rock shaft 28 having arms 29 projecting therefrom in spiral arrangement and ride ted to be engagedby certain cams 30, whi cams are pivoted on a rod 31. Each of'the'said cams is mounted by the side of a lever 32 which is connected by a link 33 with one of the numeral key levers 15. Each lever 32-has a segmental slot 34 therein and a pin 3.5 projects into saidslot from the adjacent 0211130, whereby the lever 32, when operated by a depression of the cor responding numeral key, operates the cam but with lost motion between the lever and the cam. The devices 32, which I have called levers, consist of plates or disks hav' the outline best shown in Fig. 4, and comprising a concentric art 36 for operating a universal bar, which universal bar is not shown herein, and also two concentric parts 37 and 33 with oppositely disposed ratchet teeth for cooperation respectively with fullstroke pawls 40 and 41, said pawls consisting of strips of metal extending substantially the length of the actuator and secured to rods or rock shafts 42. These pawls are controlled by the universalbar in such a fashion that, upon the down stroke of any numeral key, the pawl 41 engages the ratchet 38 to prevent u ward motion of the key until said key shal have completed its down stroke, and that upon the upstroke of said key the pawl 41 is moved out of engagement and the pawl 40 is moved into engagement with the ratchet 37 to compel a completion of the'upstroke of the key. At the lower end of the ratchet 37, the member 32 is formed with a shoulder 43 for cooperation with a key arrester consisting of a series of dogs 44 pivoted between two transverse bars 45 and 46, Fig. 2. These bars are secured together by posts 47 and in the Wahl machine they are both fixed in the end plates of the actuator. The two do 44 at the extreme ends of the system 0 dogs are con nected' together by a long link or bar 48 in such a way as to cave just enou h looseness in the series of dogs to allow 0 the operation of one of the levers 32, the construction being such that when one. of said. levers is between two of the dogs there is not room to permit of another lever operated The Walt} machine also comprises one or more addin heads 49', which adding heads are mo on the bar 20 in sucha manner that any one of said-"heads can be adjusted to any desired position alon the bar, its position determining the location of an addmg column or zone on the paper in the typewriter. Only one ad head is shown in the present inflanee. T adding heads at their lower front part ride on a wheel or roller 50 mounted on the front of the actuator 26 to assist in guiding the adding head accurately across the mm wheel, each adding head being provided with a rail or 'traclrway 51 for with said roller All of the parts above described are well known in the and I have --notdeemed it necessary to illustrate them nor to describe them in minute detail;

The mounting of the bars 45, 46 has been modified in the present instance for the purposes of myoinvention. As was said above, these two rs are secured together at intervals by poets-47 so that the two bars and the key arrester dogs constitute a unitary device. I have omitted the direct connection of the bar 46 with the vframe-work and have pivoted the bar 45 in. the end plates of A through the right-hand frame plate, as

shown in Fig. 2, where it has an arm 52 rigid? secured thereon by means of a screw 53. his frame is adapted to stand in the position shown in Fig. 4, which is the op erative position, and in which position the dogs 44 are operative to prevent the action of more than one of the levers 32 at a time. Said frame, however, normally stands in the position shown in Fig. 3, where the dogs 44 are depressed so as to be inoperative on the levers 32. The swingin of this frame is accomplished by means w ich includes a link 54 connected at its lower end with the arm 52 and at its upper end with an arm 55 projecting toward the rear from a rock shaft 56, which at its right-hand end is journaled in a bracket 57 secured to the actuator frame by a screw 58. The lefthand end of the shaft 56 is journaled at (SC in a plate 61 constituting part of a orwardly projecting section or portion of the actuator, in which ortion the master whe'el and associated devices are mounted. Near its left-hand end the shaft 56 has an arm 62 projectin therefrom toward the front oi the machine and bent ofi toward the left tc form an offset section 63, from which is bent oil a horizontal shoe 64 having an inclint 65 at its left-hand end and a second incline 66 at its right-hand end. This shoe stands in position to be cammed down by the adding head in a manner which will be understood bv reference to Figs. 2 and 4, when said shaft and at the other end to the stationary framework. The parts under the impulse limited by a stop pin 68, to arrest the arm 55.

It is desirable that the shoe on the arm 62 occupy a position nearly in front of the master wheel 27 and in this position the incline 65 of said shoe is so located that it would be arrested by the roller 50. For this reason I have formed said incline 65 with a slot 70, as shown in Fi 5, said slot being in such position that wien the shoe is depressed the roller is received within the slot. The inclines 65 are depressed by the right-hand side plate of the adding head until the bar 51 reaches the incline, when said bar rides up on the flat part of the shoe 64. The right-hand end of the bar may be beveled off as shown in Fig. 2 if necessary or desired. In Fig. 3 the shoe 64 is shown ll; section to disclose other parts to the left. 0 it.

I prefer to move the full-stroke pawls 40 and 41 out of eugagiuncnt. with the ratchets 37 and 38 when the key arrester is moved to its inoperative position shown in Fig. To this end an arm 71 is mounted on the key arrester frame and extends upward and forward, as shown in Fig. 4, said arm at its upper end being bent to form a cam 72. This arm is so arranged that when the parts move to the position shown in Fig. 3. said arm engages the pawl bar. 41 and moves it to inoperative position, as shown in Fig. 3. This bar has on it an arm 73. Fig. 2, which arm is adapted. to cooperate with an arm 74 on the pawl 40 so that when the pawl 41 is moved to the Fig. 3 position. thesiarms would cause the pawl 40 to be moved to its inoperative position also. I'Iowever, the dogs 44 themselves are adapted to press against the upper and rear surface of the pawl 4-0 and depress said pawl to the position shown in Fig. 3. It will thus be seen that means are provided for rendering the full-stroke devices inoperative at the same time that the key arrester is thrown out of action. \Vhen the key arrester is, moved up to the position motion of the ot this spring is Fig. 3, arranged trol of the universal bar and of the springs which control. these parts in the \Vahl machine, as heretofore constructed.

It will be seen that I have provided means whereby, when the typewriter and computer carriages are not in an adding zone, the key arrester and full-stroke devices are rendered inoperative, so t at the numeral keys are no longer burdene with the labor of operating them and so that said keys are no longer limited in their speed of operation by these devices; but ,when the carriages are moved into an adding zone, the parts referred to are restored to operative 6sition and condition and perform their 'unctions as usual.

Although I have here shown my invention in its adaptation to a Wahl computing machine in combination with a Remington typewriter, it will of course be understood that the invention is capable of adaptation to other styles of computin machines and typewriting machines, an that various changes can be made in the details of construction and arrangement without departing from my invention.
